Hi  Jaildar,

if you have no experience with arduino or coding at all this is a pretty big project to approach all points at once.
I.d suggest to split the project down into smaller steps. for example think about with what kind of part you want to close and open the lock. Is the door opened and closed by hand or also automated....
And also tell us more about what you want to realise. What kind of lock / door.... etc...

That statement makes sense at the human level but it is meangingless to a microcontroller. A button is a simple electro-mechanical thing that makes something happen. It can't just be replaced by a microcontroller. You need all sorts of other stuff.

Since I know nothing about how your door lock works I can't tell you what the other stuff needs to be.

Have a look at this tutorial: http://startingelectronics.com/tutorials/arduino/ethernet-shield-web-server-tutorial/

Part 5 is about having a checkbox on a webpage served out by the Arduino, checkbox controls an LED.

Then in theory it's easy to replace the LED with a solenoid which would be your door lock: http://www.ecs.umass.edu/ece/m5/tutorials/tip122_transistor_tutorial.html
